Having spent far too long trying to work out to make PHP 5 create usable password hashes for OpenLDAP from examples on the Internet (hint, comments on the md5() function on php.net are dangerously wrong), I resorted to reading the RFCs and writing the code myself. This is posted below for other people who might have the same problem.

# This will generate an MD5 sum hash.
$encrypted_password = ‘{MD5}’ . base64_encode(md5( $newpassword,TRUE)) ;

# This will generate a SHA-1 hashed password.
$encrypted_password = '{SHA}' . base64_encode(sha1( $newpassword, TRUE ));

# This will generate a SHA-1 hashed password with a salt.
$encrypted_password = '{SSHA}' . base64_encode(sha1( $newpassword.$salt, TRUE ). $salt);
